Sai Baba often asked for Dakshina. Did he ask for it from Kaka Mahajani's friend who had sworn not to give any?

No, Sai Baba did not ask for Dakshina from Kaka Mahajani's friend. This is a key point in the story from Chapter 35. The friend had made a firm resolution not to offer any Dakshina. After the friend had already broken his first resolve and bowed down, Baba asked for Dakshina, but only from Kaka Mahajani. Later in the afternoon, when they were about to leave for Mumbai, Baba again asked Kaka for Dakshina, specifically requesting seventeen rupees. On both occasions, Baba asked nothing of the friend, which, as the chapter notes, made the friend feel restless in his mind, highlighting Baba's unique way of teaching.
